Have you had experience writing pipeline processes independently?

Yes, experience in independently writing pipeline processes is usually associated with automating sequential data processing steps or build/deployment of applications.

For example, a DevOps pipeline may include stages:

• building the project,
• running tests,
• static code analysis,
• packaging artifacts,
• deploying to a test or production server.

To implement such pipelines, CI/CD tools are often used, such as Jenkins, GitLab CI, GitHub Actions, where you can describe the sequence of tasks in scripts or configuration files.

An example of a simple pipeline in GitLab CI:

stages:
  - build
  - test
  - deploy

build_job:
  stage: build
  script:
    - ./gradlew build

test_job:
  stage: test
  script:
    - ./gradlew test

deploy_job:
  stage: deploy
  script:
    - ./deploy.sh
  when: manual

This approach allows automating and standardizing the software development and release process.
